Fluorescamine is a spiro compound that is not fluorescent itself, but reacts with primary amines to form highly fluorescent products. It hence has been used as a reagent for the detection of amines and peptides. 1-100 Âµg of protein and down 10pg protein can be detected.
Yellow Fluorite. Fluorite, also called fluorspar, is a fluorescent (a word derived from its name) stone that comes in a range of colors, including red, green, blue, black and yellow. The yellow gemstones are common enough, but are rather soft, and hence not widely used in jewelry.eside black, red, green and almost all other colors, tourmaline is also available as yellow stones, though the yellow gems are very rare. The yellow gemstones come from the species of tourmaline called dravite, as well as the more valuable elbaite. The yellow rocks are mined in Brazil and Africa.
